Procedure

A process for the production of pentaerythritol phosphate alcohol (PEPA) comprising reacting in the liquid phase phosphorus oxychloride (POCl3) with pentaerythritol (PE) at a reaction temperature of at least about 100° C. in the presence of a solvent which is an alkane substituted with at least one halogen atom and having an atmospheric boiling point of about 40 to about 150° C., the reaction pressure being sufficiently high to maintain the solvent in the liquid phase, the reaction resulting in the production of PEPA and HCl by-product.

Workup

  1. customthe reaction pressure
  2. temperatureto maintain the solvent in the liquid phase
